how many numbers are divisble by 4 between 1 to 100.
Read Solution (Total 12)
-
- 4,8,12----100
4*[1,2,3-------,24,25]
Between 1 to 100 Numbers=25-1(since excluding 100)=24
so answer is 24 - 10 years agoHelpfull: Yes(15) No(1)
- given series is in A.P., i.e.,4,8,16,....96.
a=4,d=4,an=96
=>an=a+(n-1)d
=>96=4+(n-1)4
=>96=4+4n-4
=>n=96/4=24

- series is in A.P., whose 1st term is 4 and the last term is 100.
so using formula an=a+(n-1)d
100=4+(n-1)4
we get n=25.

- It is 24 only. As it is properly mentioned that the no.s should be between 1 to 100. Therefore we will not consider 100.

- including 1 and 100 we can use the formula,
(100-1)/4 + 1 , for division considering only quotient
=24 + 1
=25 answer - 10 years agoHelpfull: Yes(1) No(2)
- 100/4=25 including 100 but we need between 1 and 100 so exclude 100 then answer is 24

- 24
series 4,8....96 ap
nth term 96=4+(n-1)4...n=24 - 9 years agoHelpfull: Yes(1) No(0)
- 25 including 100
- 10 years agoHelpfull: Yes(0) No(4)
- 4,8,12,16.....100
last number -first number/4 +1
100-4/4 +1
24+1= 25 - 10 years agoHelpfull: Yes(0) No(2)
- we know that last term=a+(n-1)d
now the required series is 8,12,16,.......,96
here a=8
d=4
now using the formula we can write that
96=8+(n-1)4
88=(n-1)8
n-1=11
n=12 - 10 years agoHelpfull: Yes(0) No(0)
- 24 , because 100 is not included in the question
- 10 years agoHelpfull: Yes(0) No(0)
- we get 24 no.s which are divisible by 4 in b/n 1 to 100 by excluding 100
- 10 years agoHelpfull: Yes(0) No(0)
